Font-size changing and printing method, and host and printer therefor

Abstract

A font-size changing and printing method and a host and a printer therefor are provided. The present invention receives a before-change font size in a unit of font size generally used in software applications and an after-change font size in a unit which a user is familiar with, converts the inputted after-change font size to correspond to the unit of the inputted before-change font size, searches for the inputted before-change font size out contained in data for printing, changes the searched font size to the converted after-change font size and prints the data for printing. The present invention receives font sizes in the unit which the user is familiar with, and changes the font size and prints data in the changed font size, thereby enhancing a user's convenience.

2. The method as claimed in claim 1, further comprising printing the data for printing.

3. The method of as claimed in claim 2, wherein the printing the data for printing comprises applying the changed font size.

4. The method as claimed in claim 1, wherein the first unit of the before-change font size comprises a unit of font size used in an application by which the data for printing are created.

5. The method as claimed in claim 1, wherein the second unit of the after-change font size comprises a length unit.

6. The method as claimed in claim 1, wherein the receiving the before-change and after-change font sizes comprises receiving the before-change and after-change font sizes through a user interface provided in either a printer or a host controlling the printer.

7. The method as claimed in claim 1, wherein the changing comprises changing in either a printer or a host controlling the printer.

8. A host, comprising: an input unit for receiving a before-change font size expressed in a first unit and an after-change font size expressed in a second unit, the first unit being different from the second unit;a printer driver for converting the inputted after-change font size to correspond to the first unit of the before-change font size, searching for the before-change font size contained in font information on data for printing, and changing the searched font size to the converted after-change font size; anda communication interface unit for transmitting the changed font information to a printer together with the data for printing.

9. The host as claimed in claim 8, wherein the first unit of the before-change font size comprises a unit of font size used in an application by which the data for printing are created.

10. The host as claimed in claim 8, wherein the second unit of the after-change font size comprises a length unit.

11. A printer, comprising: an input unit for receiving a before-change font size expressed in a first unit and an after-change font size expressed in a second unit, the first unit being different from the second; anda printing unit for converting the inputted after-change font size to correspond to the first unit of the before-change font size, searching for the before-change font size out of font information contained in data for printing, changing the searched before-change font size to the converted after-change font size, and printing in the converted after-change font size.

12. The printer as claimed in claim 11, wherein the first unit of the before-change font size comprises a unit of font size used in an application by which the data for printing are created.

13. The printer as claimed in claim 11, wherein the after-change font size has a length unit.

14. A method of changing a font size, the method comprising: receiving data for printing, the received data comprising a first font having a first size expressed in terms of a first unit;receiving a second font having a second size expressed in terms of a second unit, the second unit being different from the first unit;converting the second font so as to express the second font in terms of the first unit;changing the first font in the received data to the converted second font.

15. The method of claim 14, further comprising printing the received data for printing in the converted second font.

16. The method of claim 14, wherein the first unit comprises a unit of font size used in an application by which the received data for printing is created.

17. The method of claim 16, wherein the second unit comprises a unit of length.

18. The method of claim 17 wherein the first unit comprises a unit of point and the second unit comprises a unit of at least one of centimeter (cm), millimeter (mm) and inch (in).

19. The method of claim 14 wherein the receiving the second font comprises receiving input from a user through a user interface.

20. A computer-readable medium having embodied thereon instructions for executing a font-size changing and printing method, the instructions comprising: a first set of instructions for receiving a before-changing font size expressed in a first unit and an after-changing font size expressed in a second unit, the first unit being different from the second unit;a second set of instructions for converting the received after-change font size to the first unit of the before-change font size; anda third set of instructions for searching for the before-change font size out of font information contained in data for printing, and changing the searched font size to the converted after-change font size.

21. The method as claimed in claim 20, further comprising a fourth set of instructions for printing the data for printing.

22. The method of as claimed in claim 21, wherein the fourth set of instructions for printing the data for printing comprises instructions for applying the changed font size.

23. The method as claimed in claim 20, wherein the first unit of the before-change font size comprises a unit of font size used in an application by which the data for printing are created.

24. The method as claimed in claim 20, wherein the second unit of the after-change font size comprises a length unit.

25. The method as claimed in claim 20, wherein the first set of instructions for receiving the before-change and after-change font sizes comprises instructions for receiving the before-change and after-change font sizes through a user interface provided in either a printer or a host controlling the printer.
